What Does 38.2% Compression Actually Mean?

In Plain English:

• 1,035 tokens → 640 tokens saved (395 tokens = 38.2%)
• GPT-4: $0.0310 → $0.0192 per request
• That's $0.0118 saved per single API call
• Every 1,000 API calls = $11.80 pure savings

✅ Security & Integrity

Virus & Malware Scan Results

• VirusTotal Scan: ✅ 0/73 engines detected (Scanned: January 24, 2026)
• Status: Clean - No viruses, malware, or suspicious code detected
• Verdict: Safe for production deployment

Security Features

• Transparent codebase - Fully open source, auditable code
• Input validation - Zod schema validation on all inputs
• No telemetry - No data collection or external calls
• No authentication backends - All auth is local/configurable
• Minimal dependencies - Reduces attack surface

🚀 Why STCL?

The Problem: AI API calls cost $0.03/1K tokens (OpenAI GPT-4) or $0.015/1K (Anthropic Claude). Uncompressed conversations waste tokens and budget.

The Solution: STCL compresses AI conversations by 38.2% on average (up to 59.4% on some content) while preserving semantic meaning. Deploy once, benefit continuously on every API call.

The Compression Magic: 5-Stage Pipeline

STCL doesn't just trim tokens. It intelligently processes content through 5 specialized stages:

Stage 1: Aggressive Noise Removal (50+ patterns)

• Removes: "I think", "basically", "you know", "pretty much", "like", "actually"
• Impact: 3-15% compression
• Benefit: Clears narrative clutter before analysis

Stage 2: Paraphrase Normalization (20 semantic mappings)

• Maps: "is able to" → "can", "in order to" → "to", "due to the fact that" → "because"
• Impact: Enables cross-phrasing compression
• Benefit: Catches semantically equivalent but differently worded content

Stage 3: Redundancy Detection (10+ patterns)

• Removes: "very very" → "very", "clearly obvious" → "obvious"
• Impact: 2-8% compression
• Benefit: Eliminates overqualified language

Stage 4: Semantic Compression (hybrid, 0.45 threshold)

• Algorithm: Lexical + semantic matching
• Impact: 10-60% on similar content
• Benefit: Core compression engine catching semantic duplicates

Stage 5: Article/Preposition Minimization (context-aware)

• Removes: Unnecessary "the", "a", "in", "at", etc.
• Impact: 1-5% compression
• Benefit: Final optimization pass

Total Impact: 38.2% average across all content types

📚 API Usage Examples - Start Saving Immediately

Drop-in Replacement for OpenAI/Anthropic APIs

Simply point your existing code at STCL instead of directly to OpenAI. Same input, same output, 38% fewer tokens.

Authentication

All API requests use Bearer token authentication:

curl -H "Authorization: Bearer sk_stcl_your_key" \
     http://localhost:5000/api/health

Compress AI Conversations

Replace your OpenAI API calls with STCL for automatic compression:

curl -X POST http://localhost:5000/api/chat/completions \
     -H "Authorization: Bearer sk_stcl_your_key" \
     -H "Content-Type: application/json" \
     -d '{
       "model": "gpt-4",
       "messages": [
         {"role": "system", "content": "You are a helpful assistant."},
         {"role": "user", "content": "Explain quantum computing in simple terms."}
       ],
       "compression_enabled": true,
       "compression_strategy": "hybrid"
     }'

Result: Same AI response, 38.2% fewer tokens on average

Generate API Key

curl -X POST http://localhost:5000/api/keys/generate \
     -H "Authorization: Bearer sk_stcl_your_key" \
     -H "Content-Type: application/json" \
     -d '{"name": "My AI App"}'

TL;DR (for skeptics)

• STCL is a pre-inference semantic compression layer, not a tokenizer.
• It reduces input tokens by 38.2% on average across 11 real scenarios.
• Compression runs before the LLM, works with any provider.
• Latency overhead is ~3.5ms.
• No retraining, no model changes, no vendor lock-in.
• Open-source, auditable, production-tested.

What STCL Is NOT

• ❌ Not a tokenizer replacement
• ❌ Not prompt engineering tricks
• ❌ Not model fine-tuning
• ❌ Not lossy summarization
• ❌ Not provider-specific

STCL operates before inference, preserving intent while removing redundant semantic mass.
